Abstract:
Disclosed is a display apparatus which facilitates to improve touch sensitivity by decreasing parasitic capacitance between a common electrode and gate/data lines, and decreasing delay on touch sensing and displaying driving, wherein the display apparatus may include a lower panel including a pixel electrode; an upper panel including the common electrode, wherein the common electrode together with the pixel electrode forms an electric field for displaying an image for a displaying driving mode, and the common electrode senses a capacitance change in accordance with a user's touch for a touch sensing mode; and a liquid crystal layer of VA mode formed between the lower and upper panels, and changed in accordance with the electric field between the pixel and common electrodes.
